Interleukin-33 Amplifies Human Mast Cell Activities Induced by Complement Anaphylatoxins

Frontiers in Immunology, 2021
Both, aberrant mast cell responses and complement activation contribute to allergic diseases. Since mast cells are highly responsive to C3a and C5a, while Interleukin-33 (IL-33) is a potent mast cell activator, we hypothesized that IL-33 critically ...

Complement Effectors of Inflammation in Cystic Fibrosis Lung Fluid Correlate with Clinical Measures of Disease. [PDF]

PLoS ONE, 2015
In cystic fibrosis (CF), lung damage is mediated by a cycle of obstruction, infection, and inflammation. Here we explored complement inflammatory effectors in CF lung fluid.

Complement C5a Generation by Staphylococcal Biofilms [PDF]

Shock, 2013
Biofilms production is a central feature of nosocomial infection of catheters and other medical devices used in resuscitation and critical care. However, the very effective biofilm forming pathogen Staphylococcus epidermidis often produces a modest host inflammatory response and few of the signs and symptoms associated with more virulent pathogens.

A decline of protective apolipoprotein J and complement factor H concomitant with increase in C5a 3 months after cardiac surgery—Evidence of long-term complement perturbations

Frontiers in Cardiovascular Medicine, 2022
BackgroundHeart surgery results in complement activation with the potential for collateral end-organ damage, especially if the protective elements (complement factor H, Apolipoprotein J) are inadequate. Here, we have investigated if peri-operative stress

Complement factor C5a induces atherosclerotic plaque disruptions [PDF]

Journal of Cellular and Molecular Medicine, 2014
AbstractComplement factor C5a and its receptor C5aR are expressed in vulnerable atherosclerotic plaques; however, a causal relation between C5a and plaque rupture has not been established yet. Accelerated atherosclerosis was induced by placing vein grafts in male apoE−/− mice.

Association of C5a/C5aR pathway to activate ERK1/2 and p38 MAPK in acute kidney injury – a mouse model

Romanian Journal of Laboratory Medicine, 2022
Acute inflammation is accompanied by complement system activation and inflammatory cell accumulation. Acute kidney injury (AKI) is one of the common clinical symptoms, it is not clear whether complement system-mediated signaling pathway is involved. This

Complement C5a-Induced Changes in Neutrophil Morphology During Inflammation. [PDF]

Scand J Immunol, 2017
AbstractThe complement and neutrophil defence systems, as major components of innate immunity, are activated during inflammation and infection. For neutrophil migration to the inflamed region, we hypothesized that the complement activation product C5a induces significant changes in cellular morphology before chemotaxis. Exposure of human neutrophils to

The Complement C5a-C5aR1 GPCR Axis in COVID-19 Therapeutics. [PDF]

Trends Immunol, 2020
The current pandemic of coronavirus disease (COVID-19) caused by SARS-CoV-2 is a significant global health challenge. A recent study by Carvelli and colleagues now demonstrates the involvement of complement C5a and its receptor C5aR1 in disease progression and suggests that blockade of the C5a-C5aR1 axis may represent a potential therapeutic strategy ...
